Questions & Answers

Am reading a text file that contains words, numbers and special characters, I want to remove certain special characters like: [](),'

I have this code but it is not working !

using (var reader = new StreamReader ("C://Users//HP//Documents//result2.txt")) {
            string line = reader.ReadToEnd ();

            Regex rgx = new Regex ("[^[]()',]");
            string res = rgx.Replace (line, "");
            Message1.text = res;

        }

what am I missing, thanks

Well this deletes the characters and writes it in to a new file. So here you go:

public char[] CharactersToRemove;
void Start () {
    char ch;
    int Tchar = 0;
    string directoryLoc = "C://Users//HP//Documents//";

    StreamReader reader;
    File.WriteAllText(directoryLoc + "NewResult2.txt", string.Empty);
    reader = new StreamReader(directoryLoc + "result2.txt");
    do
    {
        ch = (char)reader.Read();
        for (int i = 0; i < CharactersToRemove.Length; i++)
        {
            if (ch.Equals(CharactersToRemove*))*

{
ch = ‘\0’;
}
}
using (StreamWriter newWriter = new StreamWriter(directoryLoc + “NewResult2.txt”, true))
{
newWriter.Write(ch);
}
Tchar++;
} while (!reader.EndOfStream);
Debug.Log(“Document Cleaning Done!”);
reader.Close();
reader.Dispose();
}
